(a) Remove the top inspection
cover (1).
(b) Select the UNWRAPPED cycle and
START the cycle.
(c) When the “heat up” portion of the cycle is complete and the elapsed time
is being counted down on the display panel, pull upward on wire ring (A)
of pressure relief valve (2) with a screwdriver for approximately 3 sec-
onds; steam should discharge freely from beneath the rear of the unit.
(d) Release the wire ring of pressure relief valve (2). The steam should vent
out of the pressure relief valve until the wire ring is released. When the
wire ring is released, the valve should seat, stopping the release of
steam.
(e) Press STOP to prevent the unit from overheating.
(f) If excessive force is required to open pressure relief valve (2) or pres-
sure relief valve will not reseat properly, the pressure relief valve must be
replaced (See Calling For Service later in this manual).
(g) Install top inspection cover (1).
WARNING
The pressure relief valve
will be hot. Do not use bare
hands to pull wire ring; use a screw-
driver or rod. Failure to do so will re-
sult in burns to hands. Also, steam
will be vented from under the rear of
the sterilizer. To keep from being
burned, place a steam barrier (a rolled
up towel around the bottom of the
sterilizer.
NOTE
If the pressure relief valve does not close completely when the wire ring is re-
leased, pull the wire ring again and release it quickly so the valve snaps back
into position. Do this until the valve seats properly.
